Effect of Nanoparticles in Wood Containing Furnishes: Part 2, 2003 Spring Technical Conference Proceedings

Microparticle technology has for 22 years provided a tool to increase paper machine efficiency. The latest generations of silica based nanoparticle systems have found acceptance in the production of lightweight wood containing grades produced on demanding high speed machines providing the same classic characteristics of improved retention , dewatering , drying and sheet strength as has been experienced in wood free furnishes. Part 1 illustrated some of differences between wood free and wood containing furnishes in how these characteristics manifest on the paper machine due to the presence of extractives in the wood containing furnishes. Part 2 continues the investigation of nanoparticle effects in wood containing systems and introduces a way to measure and control extractives content in the wet end and thereby positively influence sheet properties. The equilibrium fines content in the headbox and particularly the population of wood fines in the low consistency dilution supply of a dilution headbox are strongly related to both the wet web and final sheet properties.
